Driver provides two modes of operation: Quasi Continuous Wave (quasi steady-state) mode and Pulse mode. 5.1. Quasi continuous wave mode – the oscillating mode of symmetrical unipolar meander (fig.2.). Such mode provides maximum average optical power from the LED. - Page 8 SUNSTAR传感与控制 http://www.sensor-ic.com/ TEL:0755-83376549 FAX:0755-83376182 E-MAIL:szss20@163.com Note! Please, don’t use the combination of frequency and pulse duration that gives a duty cycle more than 10 percents (table 1). Note! We recommend to use the pulse current amount to 2 A only at pulse duration less than 1 µs Otherwise used LED can be broken.
